To use this, you must hold the A button while using Z-Saber, and input the following code on the third slash. You must be holding A while it is slashing, and the code must be inputted on the third slash.
To enter these codes, have the desired Navi Customizer Program highlighted in the Navi Customizer screen. Hold the Right (->) button on the D-Pad, then enter the 10 button code (Composed of different combinations of the buttons A, B, L and R) for that NCP to compress it. Once compressed, the Navi Customizer Program's size will be reduced by one block, or square. Only non-textured programs can be compressed (AutoRun cannot be compressed either), and inputting the code again will decompress it.
After winning the End Area 5 Liberation Mission, there will be a gold Mr. Prog there who will recreate the battle. Talk to him and start the battle. Send a Navi to liberate the first item square and you should obtain 1800 Zennys. Next, retreat. You will leave the battle, however you will keep the 1800 Zennys. Repeat as many times as you want for more Zennys.
With attaching the Wireless Adapter before the Title Screen appears. Under Continue you will get Crossover Battle Mode.
With this mode you can face Shademan and link up Wirelessly to Boktai 2 to see who the fastest is to beat Shademan using the EXE 5 and Boktai 2 System.
This glitch works in the Japanese version of the game only; it was removed in the European and American versions.
First, get into a Liberation Mission and walk Medi up to a panel and select the TwinLiberate ability. Two panels (the one Medi is at and the one at the other end of the row) will be outlined in green. However, select 'No' when Medi asks you to use TwinLiberate.
Switch to another Navi (don't do anything else before this!) and take him to the second panel that was outlined in green (not the one Medi was at) and press 'A' on the panel. See how the command changed from 'Liberate' to 'TwinLiberate', and how that panel and one Medi is at are now outlined in green? Select 'TwinLiberate' and if you win, it will function exactly like Medi's ability - without the Order Point cost.
